FltLib
is a Multigen-Paradigm OpenFlight file format loader library written in
portable C. It is small and fast, and can be used to read
most
versions of the OpenFlight file format from version 14.2 to 16.x.
There are also some minor facilites to write OpenFlight files.

FltLib
is a mature library, having been in commercial use in various forms for
years.
Although some recent integration has been performed, you
should find the library stable and reliable.

Functionality

FltLib
is particularly useful for vis-sim style applications that need to be
able to load the OpenFlight file separate from the visual
representation in order to perform terrain queries or other mission
functions on the data.

FltLib has also been used to parse the OpenFlight file format in order
to build a hierarchy for scene graphs such as SGL and Nvidia's
NVSG.

Platforms

FltLib
is cross-platform and is known to work on Windows with almost all
Microsoft compilers, and should compile with GCC on most other
platforms (Linux, MacOS, etc). There is an automake project
to help on platforms where automake is supported.
